Beginning TONIGHT, Friday night, Jan. 8 at 10 p.m., and continuing until Saturday, Jan. 9 at 11 a.m., the eastbound Dulles International Airport Access Highway (DIAAH) at Dulles International Airport between mile markers 0.0 and 0.4 will be detoured to eastbound Aviation Drive. There will be alternatives for access to the DIAAH, Route 28, the Dulles Greenway and the return to the airport.

Left lane closures will begin at 9 p.m. with all lanes of traffic detouring to Aviation Drive at 10 p.m.
